SeaTunnel 是一个非常易用的支持海量数据实时同步的超高性能分布式数据集成平台

This project is a fork of https://github.com/lightbend/config, its mainly purpose is to solve these problems : * [Keep config item order in ConfigObject](https://github.com/lightbend/config/issues/365) * Change path token separator from `"."` to `"->""`. * Added `parseObjectForseatunnel()` to parse config objects in `input`, `filter`, `output` for seatunnel. * Change package name to avoid implementation conflict when using this code with the official typesafe config used by Apache Flink. If you want to do some test, please see: * Test Main Class: seatunnel-config/src/test/java/org/apache/seatunnel/config/CompleteTests.java * Config File Example: seatunnel-config/src/test/resources/seatunnel/variables.conf If you want to Package the jar: ``` git checkout garyelephant.fea.changed_package_name rm -rf ./target rm -rf ./config/target sbt package ``` then you can find `config-1.3.3.jar` in `./config/target/` --- Configuration library for JVM languages.

If you want to load config from a database or something, you would need to write some custom code. The library has nice support for merging configurations so if you build one from a custom source it's easy to merge it in. <!-- START doctoc generated TOC please keep comment here to allow auto update --> <!-- DON'T EDIT THIS SECTION, INSTEAD RE-RUN doctoc TO UPDATE --> **Table of Contents** *generated with [DocToc](https://github.com/thlorenz/doctoc)* - [Essential Information](#essential-information) - [License](#license) - [Binary Releases](#binary-releases) - [Release Notes](#release-notes) - [API docs](#api-docs) - [Bugs and Patches](#bugs-and-patches) - [Build](#build) - [Using the Library](#using-the-library) - [API Example](#api-example) - [Longer Examples](#longer-examples) - [Immutability](#immutability) - [Schemas and Validation](#schemas-and-validation) - [Standard behavior](#standard-behavior) - [Note about resolving substitutions in `reference.conf` and `application.conf`](#note-about-resolving-substitutions-in-referenceconf-and-applicationconf) - [Merging config trees](#merging-config-trees) - [How to handle defaults](#how-to-handle-defaults) - [Understanding `Config` and `ConfigObject`](#understanding-config-and-configobject) - [ConfigBeanFactory](#configbeanfactory) - [Using HOCON, the JSON Superset](#using-hocon-the-json-superset) - [Features of HOCON](#features-of-hocon) - [Examples of HOCON](#examples-of-hocon) - [Uses of Substitutions](#uses-of-substitutions) - [Factor out common values](#factor-out-common-values) - [Inheritance](#inheritance) - [Optional system or env variable overrides](#optional-system-or-env-variable-overrides) - [Concatenation](#concatenation) - [`reference.conf` can't refer to `application.conf`](#referenceconf-cant-refer-to-applicationconf) - [Miscellaneous Notes](#miscellaneous-notes) - [Debugging Your Configuration](#debugging-your-configuration) - [Supports Java 8 and Later](#supports-java-8-and-later) - [Rationale for Supported File Formats](#rationale-for-supported-file-formats) - [Other APIs (Wrappers, Ports and Utilities)](#other-apis-wrappers-ports-and-utilities) - [Guice integration](#guice-integration) - [Java (yep!) wrappers for the Java library](#java-yep-wrappers-for-the-java-library) - [Scala wrappers for the Java library](#scala-wrappers-for-the-java-library) - [Clojure wrappers for the Java library](#clojure-wrappers-for-the-java-library) - [Kotlin wrappers for the Java library](#kotlin-wrappers-for-the-java-library) - [Scala port](#scala-port) - [Ruby port](#ruby-port) - [Puppet module](#puppet-module) - [Python port](#python-port) - [C++ port](#c-port) - [JavaScript port](#javascript-port) - [C# port](#c-port-1) - [Linting tool](#linting-tool) <!-- END doctoc generated TOC please keep comment here to allow auto update --> ## Essential Information ### Binary Releases Version 1.2.1 and earlier were built for Java 6, while newer versions (1.3.0 and above) will be built for Java 8. You can find published releases on Maven Central. <dependency> <groupId>com.typesafe</groupId> <artifactId>config</artifactId> <version>1.3.2</version> </dependency> sbt dependency: libraryDependencies += "com.typesafe" % "config" % "1.3.2" Link for direct download if you don't use a dependency manager: - https://mvnrepository.com/artifact/com.typesafe/config ### Release Notes Please see NEWS.md in this directory, https://github.com/lightbend/config/blob/master/NEWS.md ### API docs - Online: https://lightbend.github.io/config/latest/api/ - also published in jar form - consider reading this README first for an intro - for questions about the `.conf` file format, read [HOCON.md](https://github.com/lightbend/config/blob/master/HOCON.md) in this directory ### Bugs and Patches Report bugs to the GitHub issue tracker. Send patches as pull requests on GitHub. Before we can accept pull requests, you will need to agree to the Typesafe Contributor License Agreement online, using your GitHub account - it takes 30 seconds. You can do this at https://www.lightbend.com/contribute/cla Please see [CONTRIBUTING](https://github.com/lightbend/config/blob/master/CONTRIBUTING.md) for more including how to make a release. ### Build The build uses sbt and the tests are written in Scala; however, the library itself is plain Java and the published jar has no Scala dependency. ## Using the Library ### API Example import com.typesafe.config.ConfigFactory Config conf = ConfigFactory.load(); int bar1 = conf.getInt("foo.bar"); Config foo = conf.getConfig("foo"); int bar2 = foo.getInt("bar"); ### Longer Examples See the examples in the `examples/` [directory](https://github.com/lightbend/config/tree/master/examples). You can run these from the sbt console with the commands `project config-simple-app-java` and then `run`. In brief, as shown in the examples: - libraries should use a `Config` instance provided by the app, if any, and use `ConfigFactory.load()` if no special `Config` is
